The invention relates in one aspect to a pressure sensor for measuring fluid pressure. The pressure sensor includes a detection chamber having a thermal sensor disposed therein. The thermal sensor includes a heating element for providing a thermal field and a sensing device for detecting a temperature response of the thermal sensor. The heating element is designed to be triggered in an oscillating manner at at least one frequency. The pressure of the fluid can be determined based on the temperature response of the thermal sensor. The thermal sensor is positioned on a carrier film that is held by the carrier structure and extends over the cavity. Furthermore, a hole is present which enables a pressure equalization between the cavity and the inner region of the detection chamber. The invention relates, in other aspects, to a method for measuring the pressure of a fluid and to the use of a pressure sensor according to the invention for monitoring.
